The present invention provides a method for identifying and characterizing candidate fluorescent molecules. This method involves the generation of spatially addressed arrays of heterocyclic compounds which are candidate fluorescent molecules. The spatially addressed array can be used to identify fluorescent molecules among the candidate molecules. The spatially addressed array can be used to determine the optical characteristics of one more candidate molecules. The invention also provides methods for making such arrays of heterocyclic compounds. In a specific embodiment, synthetic methods are provided for synthesis of triarylpyridines, particularly unsymmetric triarylpyridines. n preferred embodiments, the present invention provides novel heterocyclic fluorescent compounds having deazalumazine, cyanopyridine or pyrimidine cores. Heterocyclic fluorescent compounds of this invention are useful as dyes to label molecules such as nucleic acids, peptides and proteins, and particularly antibodies. In other embodiments, the novel heterocyclic fluorescent compounds are useful as dyes to label cellular compartments and organelles. The novel heterocyclic fluorescent compounds can also be used as sensors or indicators of specific metal ions, chemical warfare agents and pH.

We report a method for the efficient construction of small molecule macroarrays using microwave-assisted SPOT-synthesis. Macroarrays of 1,3-diphenylpropenones (chalcones) were synthesized rapidly and in high purity starting from robust, Wang-linker-derivatized planar supports. We have optimized the entire chalcone macroarray construction process and evaluated the efficiency and utility of microwave-assisted reactions in array synthesis. Microwave heating was found to be most beneficial for reactions that require temperatures greater than the boiling points of the solvents. These microwave-assisted conditions permitted straightforward access to macroarrays of 2,4,6-triarylpyridines derived from the original chalcone scaffold. (c) 2006 Elsevier Ltd. All rights reserved.

e and 4β-cinnamido linked podophyllotoxin congeners have been synthesized. All the twenty nine compounds were evaluated for anticancer activity against five human cancer cell lines (A-549, A375, MCF-7, HT-29 and ACHN). Some of the synthesized compounds showed good anticancer activity that is comparable to etoposide. The IC50 of compounds 17a and 17f is 2.7 and 2.1 μM respectively against A-549 cancer
